1 Claim. i

The invention relates to air moisteners and an object of the invention is to provide an air moistener adapted to be attached to the exhaust end of a tank type vacuum cleaner.

Another object of the invention is to provide an air moistener of the character indicated above adapted to receive air under 'pressure from a vacuum cleaner and conduct air into a container for liquid or ice after which the air discharges into the atmosphere.

Another object of the invention is to provide an. air moistener embodying an air moistening medium including chlorophyl or the like to deodorize the air of the room being cleaned.

Other objects of the invention not specifically mentioned may appear in the following Specification describing the invention with reference to the accompanyin drawing illustrating a preferred embodiment of the invention. It is however, to

be understood, that the invention is not to be limited or restricted to the exact construction and combination of parts described in the specification ancl shown in the drawing, but that such changes and modifications can be made, which 'fall within the scope of the claims appended hereto. In the several figures of the drawing similar parts are designated by similar reference characters and Figure 1 is a view in front elevation of an air moistener constructed in accordance with an embodiment of the invention, the connection hose being omitted.

Figure 2 is a view partly in rear elevation and partly in section of the device as herein comprised; and

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure 1, an associated hose connection being indicated in fragment.

The air moistener embodied herein comprises a bottom member I I] of substantially square horizontal cross section adapted to receive liquid or ice through its open top. This container l forms the bottom chamber of the air moistener embodied herein and a top member T having a shape similar to the member I0 is pivotally secured to the rear top edge portion of the member I [I preferably by means of a piano hinge i I. The top member T forms the upper or condenser chamber of the air moistener. Between the top ed e surface of the Walls of the chamber In and the bottom [2 of the top member T is arranged a sealing gasket l3 and the two members T and It! are secured tightly together by cooperating looking or latching means mounted on said portions, preferably by a latch I4 of a well known conthe two moistener portions. Approximately centrally of the top member T of the moistener a tube l5 extends vertically through the bottom [2 of said portion and. the seam is about the tube is sealed air tight. The tube extends. downwardly to within a very short distance of the bottom ll of the lower portion Ill of the air moistener and the lower end of said tube is closed by means of a sieve-like perforated disk 58 or the like.

An inlet port 19 provided in and centrally of the front wall 20 of the top moistener .portion T and a tubular nipple 2| is adapted to be connected by means of a hose 22 or the like to the outlet of a vacuum cleaner and if desired retainer clips 24 may be provided on the nipple 2| to improve the connection between said nipple and said hose. Two upright baflle plates 25 are securely mounted on the tube l5 diametrically opposite to each other and extend laterally therefrom to form relatively narrow passage ways 26 with the side walls 21 of the top portion T of the air moistener.

An air inlet opening 28 is provided in the circumferential wall of the tube l5 opposite the inlet port l9, so that a part of the air entering through said port under pressure is forced into the tube I5.

The top portion T of the air moistener is closed by a cover 29. A tube 30 fits slidably into the tube [5. The upper end of the tube 30 ex- .tends through the cover 29 and is shaped to form a grip 3| to enable an operator to impart rotary movement to the tube 30, which is provided in its wall with an inlet opening 32 of a size and shape similar to the inlet opening 28 in the tube [5 with which it is to be moved into and out of registry to regulate the amount of the air admitted to the lower portion or container l0.

Rearwardly of the tube l5 an elongated opening 33 is provided in the bottom l2 of the top portion T of the air moistener and extends parallel to the baiiie plates 25. A flattened tube 36 is securely fitted into said elongated opening and extends upwardly from the bottom 52. In the top wall 29 and rear wall of the top portion T- of the moistener vents 38 are provided.

When the air moistener is to be used liquid or ice is inserted into the container I through its open top, after the latch 14 has been disconnected and the top portion has been pivoted about thehinge ll into open position a small amou t Q chlorophyl may be added to the liquid. Then the top portion is closed and secured in this position by the bayonet latch M. The hose 22 is connected to the nipple 2i and leads from the outlet of a vacuum cleaner whereby air under pressure is delivered into the top member T. A part of this air by-passes the hafiie plates 25 and a part is forced through the adjusted overlying openings 28 and 32 into and through the pipes l5 and 30 into the container I 0, where the air is washed and moistened and eventually cooled by the liquid or the ice in the container. The treated air rises through the elongated opening 33 and the flattened tube 34 and mixe with the dry air in, the upper member T. This moistened air mixture exhausts through the vents 36.

The tube l5 closely adjacent to its lower or free end is provided therearound in its wall with the openings 31. These openings are of advantage as they are of less depth in the member T than the openings in the disk 18, require less pressure to release the air and will at times perform their function when air is not coming from the bottom.

The above description shows clearly that an air moistener as embodied herein can be easily attached to the outlet end of the tank or other outlet of a vacuum cleaner and that the air forced through said device is moistened by the liquid or the ice in the container. small amount of chlorophyl with the liquid in the container the air is deodorized and freshened.

I claim:

In an air moistener, a casing formed to provide an upper compartment and a lower compartment, said lower compartment having an open top and said upper compartment hingedly connected with the lower compartment and having a bottom wall adapted to cover the open top of the latter when it is normally disposed, said lower compartment being adapted to receive a liquid cooling medium, baiiles dividing the interior of said upper compartment with certain of the edges thereof spaced from opposed walls of the latter to provide relatively narrow passageways there- By mixing a 2 between, an inlet for air under pressure opening into said upper compartment at one side of said baffles, means centered between adjacent ends of said baffles for conveying a relatively large volume of the incoming air into said lower compartment and discharging the same in proximity to the bottom thereof, means for conveying the moistened air from above the cooling liquid within said lower compartment and discharging it into the upper compartment at the opposite sides of said baffles, outlets opening through certain of the walls of said upper compartment at the same sides of said bafiles for the discharge of a mixture of the unmoistened and moistened air outwardly therethrough, the first named means comprising a tubular element depending through the top and bottom Walls of said upper compartment with its lower end disposed in closely spaced relation with respect to the bottom of said lower compartment, a second tubular element depending within the first named tubular element, aknob-like cap closing the upper end of said second tubular element for turning the same relatively to the first named tubular element, the first named tubular element having a side opening disposed substantially in line with the said air inlet to said upper compartment, and said second tubular element having a side opening adapted to be moved into and out of registry with the first named opening to regulate the air flow into said lower compartment.
